Re: Check This Out - ntl 100Mbps
 

Doesnt breed confidence, what does this mean, ntl will refuse to get the lower reaches of their footprint caught up in favour of getting a few areas ahead for PR reasons?

Someone posted on another forum it would make sense to put the trial in ntl's worst areas. In other words why not spend the money where its needed anyway and upgrade these areas a few generations in one go so it doesnt need doing again for a while.

the chetnet link gives me this.

No Thread specified. If you followed a valid link, please notify the administrator

someone got cold feet publishing the info?

I read also on a pcpro link that bittorent are involved and ntl will use some kind of p2p technology to optimise the network.

He is reffering to 100mbit lan, a 10mbit xfer isnt really stressing your lan hardware.

I can fault their service. Peak time congestion on my ubr is approximately 18 hours a day.

Re: Check This Out - ntl 100Mbps
 

Cable giant NTL is to field test a 100Mbits/sec broadband service for homes from March at Ashford in Kent, the company revealed today.
The trial, which we flagged last week, is basically of a bandwidth-on-demand system †“ you get 100Mbits/sec when you need it, for instance to download movies.
NTL staged a demonstration at a show flat in Pimlico, London, in which the system delivered three high-definition TV streams simultaneously, leaving bandwidth to spare for other internet uses.
Kevin Baughan, NTL's director of network strategy, pointed out that cable has far more capacity than ADSL+, the latest version and fastest broadband technology to use existing phone lines. That can deliver at most 20Mbit/sec to users close to the exchange, but speeds fall off rapidly with distance because there is no way to boost the signal.
NTL takes fibre with virtually unlimited bandwidth to neighbourhood boxes, where the signals are transferred to a twin cable known as Siamese because it is 'joined at the hip'. One half is coax cable, carrying about 3Gbits/sec, and the other carries three copper twisted pairs for telephony. The latter gives NTL an extra option of delivering ADSL2+ to the home.
But the 100Mbit trial uses the coax half, the new DOCSIS 3.0 cable-data standard, and a wideband modem from Arrisi with technology that segments the available bandwidth into broadcast TV, Video-on-demand, downloads, and ordinary internet traffic

That's Dolphin Square, which is in Pimlico. It wasn't DOCSIS 3.0 last time I looked but you never know - they've got to test it somewhere.

P.S. That PCPro article has an unintended advertising link on it!

Re: Check This Out - ntl 100Mbps
 

Dolphin Square Pimlico was fibre to the home as I remember.

Chrysalis, sadly that same 'everyone must be the same' attitude is what, without LLU, would have badly held back the UK. We can't all have the same. You'll probably find that ntl aren't paying much if anything for this trial, it'll be gratis based on the large amounts of cash Arris might make from ntl if it goes well and ntl start migrating from Cisco to Arris.

Again this is a TRIAL it's not a live deployment. The trial area will probably be a single node for God's sake. Can hardly extrapolate a rollout over 12 million passed homes based on a single node.

Analogue switchoff is coming. It's not as easy as flicking a switch.

Regarding that article, the telco and CATV are not fed by the same fibre. It's also not using DOCSIS 3, it's using a proprietary Arris technology.The writer of the article extrapolated to things he knows nothing about.

Ethernet over coax is one of the technologies alongside the CATV/DOCSIS approach and VDSL thats under evaluation.

Re: Check This Out - ntl 100Mbps
 

you can probably register for the TRIAL on the site that NTL normally run there trials on . There used to be a general link but you may need to be registered Pointman is the NTL trials guy there

Re: Check This Out - ntl 100Mbps
 

ok thanks for the extra explanation ignition.

Re: Check This Out
 

Oh so true... ;)

Re: Check This Out - ntl 100Mbps
 

Has anybody read the news on ADSLGuide? Its like they have read this thread but got their wires crossed :D

Re: Check This Out - ntl 100Mbps
 

this may sound like a flame but it aint ment that way ! what makes you think that this site hasn't "got their wires crossed"?
I dont see official press releases here and the resident networking expert wasn't spot on and the only other NTL person I see commenting said

Re: Check This Out - ntl 100Mbps
 

Has anyone seen this, hope i'm not reposting old stuff.

Re: Check This Out - ntl 100Mbps
 

Thids may have been asked/answered already but at speeds of 100meg per sec would current hard drives be able to cope with the speed of the data being fed to it

cheers

Re: Check This Out - ntl 100Mbps
 

I'm no tech :p:

But to quote a piece from Western Digital's site:

"Fast 7200 RPM spindle speed and SATA 150 MB/s interface".

One of their slower drives.

Re: Check This Out - ntl 100Mbps
 

Theoretically USB 2.0 should be able to cope. I hope to [insert deity of your choice] that they don't go down that route though! It's only* 12.5Mbytes/second after all. Servers and modern workstations with gigabit ethernet connections can throw far more than that across the wires with no obvious detriment.

* cripes...how far we've come since 28800 baud analogue modems.

Re: Check This Out - ntl 100Mbps
 

See post #95 above. Apparently it uses a gigabit ethernet connection.
